Public Beverage(String name, BigDecimal cost) * this case it takes the arguments used to initialize the attributes of the class.
* This is the constructor, which is used to create instances of the class. private so that they can only be accessed from within the class. These are the attributes (fields) of the class. * This is the way classes are defined in Java, the public bit just says it's visible I imagine to a non-programmer, step 2 doesn't make much sense, so here's some code (which I hope makes it a bit clearer): /** A class typically has attributes (the data that will make instances unique) and behaviour (operations based on that data) though you'd don't neccessarily have to have both as you can see from the code below. When presented with a problem, like that in step 1, a good rule of thumb in deciding what the classes should be is to look at the nouns - in this case beverage, menu and order look like good candidates. Modern computer languages use a technique call Object Orientation, which in a nutshell involves describing the entities in general terms to create what is known as classes. You multiple the price of each beverage by the quantity to get the cost of the order. An order comprises of one or more beverages from the menu in varying quantities. Think about what's involved if you were going to do this on paper - you'd have a list of beverages each with a name and a price (the menu). This answer is in just that order, first I'll explain what I think the key points are (sure I've missed some, as much of this is second nature) then I'll give you pointers on how to run the code. There's concepts of how a program should be structured to contend with after which comes the compilation and running. Having written the answer out this is quite a complex task for a non-programmer. How do i even start this? i'm a law student but got forced to do this please do help me out your kindness would be repayed thanks in advance Return the price of the item using the following method signature: double processItem(int input) In your code, you must create a method to process the item choice and UponĬompletion of the ordering, the program will display the total amount of
Then, it will let theĬustomer to choose the each item according to his/her preference. To decide how many items he/she wish to order. Program to take the restaurant customer order.
Here is Pizza.java import “OOP Restaurant” owner has engaged you to write a Java This is the attempt I have made using OOP in mind as I thought that would be just the way to go. I was inspired by a previous post here that also wrote a pizza ordering application.
